Paraesophageal Hernia (PEH) Is A Type Of Hernia In Which The Gastroesophageal Junction Between The Stomach And The Esophagus Does Not Move Normally, Allowing The Stomach To Move Up Through The Chest Cavity. This Form Of Hernia Is Considered More Serious Than Other Types Of Hernias Because Of The Potential For Complications. Symptoms Of PEH Include Chest Pain, Difficulty Swallowing, And Heartburn. Other Symptoms May Include Vomiting, Nausea, And Coughing. The Cause Of PEH Is Not Known, But Some Contributing Factors May Include Weakened Abdominal Muscles, Injury To The Abdominal Area, And Tissue Damage Due To A Previous Surgery. Diagnosis Of PEH Is Typically Made Based On Physical Examination, Imaging Tests, And Endoscopy. Treatment For PEH May Involve Lifestyle Changes, Medications, Or Surgery. Surgery Is Often Recommended To Prevent Further Complications And To Alleviate Symptoms. PEH Can Be A Serious Condition And Can Lead To Complications Such As Obstruction Of The Esophagus, Gastric Volvulus, And Perforation Of The Stomach. It Is Important To Seek Medical Attention If You Are Experiencing Any Symptoms Of PEH. Early Diagnosis And Treatment Can Help Avoid Further Complications And Improve Outcomes.
